Grateful of help for a complete newbie. I have set up on Zorro and linked it to an Oanda demo account. It seems to connect (green light), but receive the following error messages (Z1). Not sure if it is to do with antivirus software (Bitdefender) blocking Zorro access to data files or something else. Any ideas?
